I'm coding a Family Feud game in C# and after each answer is submitted the 30-second timer is supposed to reset. The problem is I'm accumulating 1-second Intervals so that the counter is counting down faster and faster. I can't figure out how to prevent the Intervals from accumulating. I want it to stay a fixed 1 seconds no matter how many times the button is pressed.
Code:
public System.Windows.Forms.Timer _timer = new System.Windows.Forms.Timer();
public int time = 30;
private void Check_Click(object sender, RoutedEventArgs e)
{
time = 30;
_timer.Tick += timer_Tick;
_timer.Start();
uxLabel1.Content = time.ToString();
//additional code
}
private void timer_Tick(object sender, EventArgs e)
{
_timer.Interval = 1000;
time--;
if (time == 0)
{
_timer.Stop();
strike();
}
uxLabel1.Content = time.ToString();
}
Don't put _timer.Tick += timer_Tick; in the button click code, put it once in the constructor of your form and have that be the only event registration.
public partial class YourForm : Form
{
public YourForm()
{
InitializeComponets();
_timer = new System.Windows.Forms.Timer();
_timer.Tick += timer_Tick;
_timer.Interval = 1000;
}
private System.Windows.Forms.Timer _timer;
private int time = 30;
private void Check_Click(object sender, RoutedEventArgs e)
{
time = 30;
_timer.Start();
uxLabel1.Content = time.ToString();
//additional code
}
private void timer_Tick(object sender, EventArgs e)
{
time--;
if (time == 0)
{
_timer.Stop();
strike();
}
uxLabel1.Content = time.ToString();
}
}

I have 5 Forms, 1 main form, and 4 forms I want them to switch between each other Automatically every couple of seconds (take turns, each form x seconds and switch to the next).
I have 2 forms so far switching between each other every 2 seconds.
void mytimer_Tick(object sender, EventArgs e)
{
if (!frm2.Focused)
frm2.Focus();
else
frm3.Focus();
}
private void Form1_Load_1(object sender, EventArgs e)
{
Timer mytimer = new Timer();
mytimer.Tick += mytimer_Tick;
mytimer.Interval = 2000;
mytimer.Start();
}
Thankyou.
Crude format. But you will get the idea.
private void HideAllForms()
{
frm1.Hide();
frm2.Hide();
frm3.Hide();
frm4.Hide();
}
void mytimer_Tick(object sender, EventArgs e)
{
if (frmSrl == 1)
{
frmSrl++;
HideAllForms();
frm1.Show();
}
else if (frmSrl == 2)
{
frmSrl++;
HideAllForms();
frm2.Show();
}
else if (frmSrl == 3)
{
frmSrl++;
HideAllForms();
frm3.Show();
}
else if (frmSrl == 4)
{
frmSrl =1;
HideAllForms();
frm4.Show();
}
else
frmSrl = 1;
}
int frmSrl = 1;
private void Form1_Load_1(object sender, EventArgs e)
{
Timer mytimer = new Timer();
mytimer.Tick += mytimer_Tick;
mytimer.Interval = 2000;
mytimer.Start();
}
I have a timer in a console app:
using System.Timers;
Timer Timer = new Timer();
I gave it an interval, and it does stuff at _timer_Elapsed method periodically:
Timer.Elapsed += _timer_Elapsed;
Timer.Enabled = true;
private static void _timer_Elapsed(object sender, ElapsedEventArgs e)
{
...
}
How can I create a second timer that counts down until this timer starts?
Create a second timer that elapses every second and use the following code to count down and a write message to the console.
#define COUNTDOWN_SECONDS 10
private int CountDownValue = COUNTDOWN_SECONDS;
private static void _timer2_Elapsed(object sender, ElapsedEventArgs e)
{
WriteConsoleMessage(CountDownValue--);
if (CountDownValue == 0)
{
// Stop timer2
// Start timer1
}
}
private static void WriteConsoleMessage(int Value)
{
if (Value < COUNTDOWN_SECONDS)
Console.CursorLeft = 0; // Reset cursor to start of the line
Console.Write(string.Format("{0} Seconds until timer starts", Value.ToString());
}
Heres how i did it:
public static int Interval = 5000;
public static int IntervalLeft = Interval;
Timer.Elapsed += _timer_Elapsed;
Timer.Enabled = true;
Timer.Interval = Interval;
CountDownTimer.Elapsed += _CountDowntimer_Elapsed;
CountDownTimer.Enabled = true;
CountDownTimer.Interval = 1000;
CountDownTimer.Start();
private static void _timer_Elapsed(object sender, ElapsedEventArgs e)
{
CountDownTimer.Stop();
Timer.Stop();
DOES THE JOB HERE
Timer.Start();
CountDownTimer.Start();
IntervalLeft = Interval;
}
private static void _CountDowntimer_Elapsed(object sender, ElapsedEventArgs e)
{
Zipper.ClearCurrentConsoleLine();
IntervalLeft = (IntervalLeft - 1000);
Console.Write("Starts in" + IntervalLeft/1000);
}
The first timer one stops the second timer when it elapses...
How can I change the text of button with timeout? I tried out with the following code but it is not working.
private void button1_Click(object sender, EventArgs e)
{
Stopwatch sw = new Stopwatch();
sw.Start();
if (button1.Text == "Start")
{
//do something
button1.Text = "stop"
if (sw.ElapsedMilliseconds > 5000)
{
button1.Text = "Start";
}
}
How can I correct my code?
You need to use Timer instead:
Timer t = new Timer(5000); // Set up the timer to trigger on 5 seconds
t.SynchronizingObject = this; // Set the timer event to run on the same thread as the current class, i.e. the UI
t.AutoReset = false; // Only execute the event once
t.Elapsed += new ElapsedEventHandler(t_Elapsed); // Add an event handler to the timer
t.Enabled = true; // Starts the timer
// Once 5 seconds has elapsed, your method will be called
void t_Elapsed(object sender, ElapsedEventArgs e)
{
// The Timer class automatically runs this on the UI thread
button1.Text = "Start";
}
Stopwatch is only for measuring how much time has passed since you called Start().
If you're using C# 5
private async void button1_Click(object sender, EventArgs e)
{
button1.Text = "Stop";
await Task.Delay(5000);
button1.Text = "Start";
}
You could use a timer. In this example the text of the button changes to "Stop" after 5 seconds.
private Timer timer = new Timer();
private void button1_Click(object sender, EventArgs e)
{
timer.Interval = 5000; // interval length
timer.Tick += TimerOnTick;
timer.Enabled = true; // activate timer
button1.Text = "Start";
}
private void TimerOnTick(object sender, EventArgs eventArgs)
{
timer.Enabled = false; // deactivate timer
button1.Text = "Stop";
}
I think you can reach your goal by using Timer
Example of using Timer
public partial class FormWithTimer : Form
{
Timer timer = new Timer();
public FormWithTimer()
{
InitializeComponent();
// Everytime timer ticks, timer_Tick will be called
timer.Tick += new EventHandler(timer_Tick);
timer.Interval = (1000) * (1); // Timer will tick every second
timer.Enabled = true; // Enable the timer
}
// .......
showForm() // declaration
{
timer.start();
// .......
timer.stop();
}
void timer_Tick(object sender, EventArgs e)
{
//hide form...through visibility
}
}
Use this instead of Stopwatch:
private void button1_Click(object sender, EventArgs e)
{
button1.Text = "stop"
aTimer = new System.Timers.Timer(5000);
aTimer.Elapsed += new ElapsedEventHandler(OnTimedEvent);
aTimer.Enabled = true;
}
// Specify what you want to happen when the Elapsed event is raised.
private static void OnTimedEvent(object source, ElapsedEventArgs e)
{
button1.Text = "Start";
var atim = source as Timer;
if (atim != null)
atim.Elapsed -= OnTimedEvent;
}
I have a Windows.Forms.Timer in my code, that I am executing 3 times. However, the timer isn't calling the tick function at all.
private int count = 3;
private timer;
void Loopy(int times)
{
count = times;
timer = new Timer();
timer.Interval = 1000;
timer.Tick += new EventHandler(timer_Tick);
timer.Start();
}
void timer_Tick(object sender, EventArgs e)
{
count--;
if (count == 0) timer.Stop();
else
{
// Do something here
}
}
Loopy() is being called from other places in the code.
Try using System.Timers instead of Windows.Forms.Timer
void Loopy(int times)
{
count = times;
timer = new Timer(1000);
timer.Enabled = true;
timer.Elapsed += new ElapsedEventHandler(timer_Elapsed);
timer.Start();
}
void timer_Elapsed(object sender, ElapsedEventArgs e)
{
throw new NotImplementedException();
}
If the method Loopy() is called in a thread that is not the main UI thread, then the timer won't tick.
If you want to call this method from anywhere in the code then you need to check the InvokeRequired property. So your code should look like (assuming that the code is in a form):
private void Loopy(int times)
{
if (this.InvokeRequired)
{
this.Invoke((MethodInvoker)delegate
{
Loopy(times);
});
}
else
{
count = times;
timer = new Timer();
timer.Interval = 1000;
timer.Tick += new EventHandler(timer_Tick);
timer.Start();
}
}
I am not sure what you are doing wrong it looks correct, This code works: See how it compares to yours.
public partial class Form1 : Form
{
private int count = 3;
private Timer timer;
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
Loopy(count);
}
void Loopy(int times)
{
count = times;
timer = new Timer();
timer.Interval = 1000;
timer.Tick += new EventHandler(timer_Tick);
timer.Start();
}
void timer_Tick(object sender, EventArgs e)
{
count--;
if (count == 0) timer.Stop();
else
{
//
}
}
}
Here's an Rx ticker that works:
Observable.Interval(TimeSpan.FromSeconds(1))
.Take(3)
.Subscribe(x=>Console.WriteLine("tick"));
Of course, you can subscribe something more useful in your program.
you may have started the timer from another thread, so try invoking it from the correct thread.
for example, instead of:
timerX.start();
Use:
Invoke((MethodInvoker)delegate { timerX.Start(); });
Check if your timer in properties is enabled.
Mine was false and after setting to true it worked.
If you are using Windows.Forms.Timer then should use something like following.
//Declare Timer
private Timer _timer= new Timer();
void Loopy(int _time)
{
_timer.Interval = _time;
_timer.Enabled = true;
_timer.Tick += new EventHandler(timer_Elapsed);
_timer.Start();
}
void timer_Elapsed(object sender, EventArgs e)
{
//Do your stuffs here
}
If you use some delays smaller than the interval inside the timer, the system.timer will execute other thread and you have to deal with a double thread running at the same time. Apply an InvokeRequired to control the flow.
Hi I am working with Windows.Forms.Timer with Web Application . I create Timer.Tick event handler to handle Timer_Tick but I am not successfull. I don't get any error but I can not get result even. Here is my code
System.Windows.Forms.Timer StopWatchTimer = new System.Windows.Forms.Timer();
Stopwatch sw = new Stopwatch();
public void StopwatchStartBtn_Click(object sender, ImageClickEventArgs e)
{
StopWatchTimer.Enabled = true;
StopWatchTimer.Interval = 1;
StopWatchTimer.Start();
this.StopWatchTimer.Tick += new EventHandler(StopWatchTimer1_Tick);
sw.Start();
}
protected void StopWatchStopBtn_Click(object sender, ImageClickEventArgs e)
{
StopWatchTimer.Stop();
sw.Reset();
StopWatchLbl.Text = "00:00:00:000";
}
public void StopWatchTimer1_Tick(object sender,EventArgs e)
{
TimeSpan elapsed = sw.Elapsed;
StopWatchLbl.Text = string.Format("{0:00}:{1:00}:{2:00}:{3:00}",
Math.Floor(elapsed.TotalHours),
elapsed.Minutes,
elapsed.Seconds,
elapsed.Milliseconds);
}
From the MSDN documentation for Windows Forms Timer (emphasis mine):
Implements a timer that raises an event at user-defined intervals. This timer is optimized for use in Windows Forms applications and must be used in a window.
This timer will not work in a web application. You'll need to use another class, like System.Timers.Timer. This has it's own pitfalls, however.
Did you try defining the Tick event prior to starting the timer?
this.StopWatchTimer.Tick += new EventHandler(StopWatchTimer1_Tick);
StopWatchTimer.Start();
public partial class TestFrom : Form
{
private Thread threadP;
private System.Windows.Forms.Timer Timer = new System.Windows.Forms.Timer();
private string str;
public TestFrom()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
Timer.Interval =100;
Timer.Tick += new EventHandler(TimeBussiness);
Timer.Enabled = true;
Timer.Start();
Timer.Tag = "Start";
}
void TimeBussiness(object sender, EventArgs e)
{
if (threadP.ThreadState == ThreadState.Running)
{
Timer.Stop();
Timer.Tag = "Stop";
}
else
{
//do my bussiness1;
}
}
private void button3_Click(object sender, EventArgs e)
{
ThreadStart threadStart = new ThreadStart(Salver);
threadP= new Thread(threadStart);
threadP.Start();
}
private void Salver()
{
while (Timer.Tag == "Stop")
{
}
//do my bussiness2;
Timer.Start();
Timer.Tag = "Start";
}
}
